Good-Win Racing Mazda Performance Parts

Miata MX5 2006-2015 · 2.5 Liter Engine Conversions


Good-Win Racing has long specialized in 2.5 conversions for the NC Generation Miata.  We raced and set track records in the first serious 2.5 liter fully caged NC (Project NC LIGHT detailed in our forum) and later developed our dual purpose street/autocross/track "Project Blue" shown above..  The reason to use the 2.5 is easy to understand, it's a bigger Mazda factory motor that is easily installed into the NC Generation Miata for a reliable normally aspirated 200 hp Miata when trimmed with all our 2.5 goodies below.   Or add boost and make 300 HP and more! Our Project BLUE shown above with our big 1.8 Inch Header and a custom built 2.5 liter running on E85 and making over 220 hp at the wheels!  We do these installs here...and we sell you the parts below to help YOU get the most from your 2.5 conversions.

REVIEWS

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.

Hi There Good-Win Racing. I just wanted to thank you guys so much for the great customer service and quality parts. My 91 MX-5 is running awesome thanks to the parts I put on it from your website, racing beat sway bars, racing beat endlinks, racing beat muffler, magnaflow catalytic con, shifter parts, and a few more. Thank you so much for making your website so knowledgeable and easy to get all these awesome MX-5 parts. My MX-5 handles, drives, and sounds awesome with all the new parts, Thanks a Million!! I look forward to ordering a new exedy performance clutch and light weight flywheel from Good-Win Racing in a couple months.
